Abstract
A clock signal outputting method in which either a clock signal based on a signal from the outside or an alternative clock signal from a fixed oscillator is selected and outputted, wherein, when the clock signal is selected to be outputted, the fixed oscillator is put into non-operating state, and when any error occurs in the clock signal, the fixed oscillator is operated to output the alternative clock signal.
